I dont think closed means that well it could for you but StarCraft 2 got a closed beta with videos all around the internet.

Closed beta means you won't be able to participate without an invitation or key from the game's developer. Some require you sign NDAs (Non-Disclosure Agreements) that prevent you from posting any public information about the unfinished game, while others do not, or have phase-specific rules.

StarCraft 2's initial phases of closed beta were invitation only and had an NDA attached.
StarCraft 2's last few phases of closed beta were invitation only but had no NDA attached.
All of Dawn of Fantasy's phases of closed beta are invitation only and have an NDA attached.

Open betas, which are open to the general public and do not require invitations, never have NDAs attached as anyone who wants information on the game can simply download their own client.

since the next beta test email have not sent out yet(should be sooner or later)
is there any way for us to know or to found out if we are qulifey or not
so if one is not qulifey he do not have to hope so much until the end
and maybe then those who might still can try and imporve to increase there chances to be part of the beta test
